Rust can be caused due to a variety of reasons. It mainly attacks metallic surfaces that are exposed to increased moisture and oxygen. With the passage of time, rust can cause excessive damage to the metallic surface, and if you have a wall in the house that is made of metal, there’s no way you can paint on it until you get the rust removed. However, there are plenty of different ways by which you can tackle the rust-related problem first before you start painting. Due to the fact that rusting creates holes in the walls and often causes an uneven texture, it’s important that you follow the steps mentioned below before you start painting.
Step 1: How to Remove the Light Rust
Before you move onto the heavily afflicted areas, you will first need to remove the light rust from the wall. You can use a wire brush in order to remove the flakes as well as the powdery rust on the surface of the wall, then cover it up by using a rust-inhibitive primer. While the old wall may look terrible due to the onset of rust, all it takes is a little bit of preparation to make it look as good as new. You can’t begin unless you have cleaned out those tiny flakes and areas with the light rusting, as they will often prevent the paint from properly adhering to the walls. A little bit of prep work is all you need to do before you actually get started with the paint job.
Step 2: Use a Grinder or a Sander
Now that the areas with light rust have been removed, the next step is to focus on areas that have excessive rusting. For that purpose, you will need to purchase a grinder or a sander. Grinders and sanders are readily available in a variety of different shapes and sizes, and are also available to rent. You can even rent one from your local market. A grinder can be fitted with a stripping disc or a grinding wheel before you can start using it. Regardless of the tool you use, you have to make sure you use the coarsest abrasive available to you in order to remove the pockmarks and the areas that have been heavily rusted.
Step 3: Apply Primer
Once you have removed the rust from the walls, your next step would be to apply the primer on the surface. Using a rust-inhibitive primer is obviously a better idea, as that will ensure that rust doesn’t begin setting on the walls again. You can use a roller in order to apply the primer on the surface of the wall in neat, even lines. Once the primer has been applied, you can then start with the application of a fresh coat of paint. These are some basic steps you need to follow in order to remove the dust before you paint it.
